Goscilowicz family search in Poland (& Juchniewicz on female side from Lithuania) 1. Open

I am trying to find ancestors in Poland.   My father, Edek Goscilowicz, came to UK during the war as a Polish refugee with Anders Army.   I have very few family left in Poland, but I am still in contact with a cousin in Kielce.  I recently met a lady in my home town and we discovered that we have the same historical family name of Goscilowicz.   Her grandfather’s name was Goscilowicz and he emigrated from Lithuania.    My family had family in Lithuania as well.  They were isolated from family in Poland when the borders changed after WW11.
I have tried to find out more about my fathers escape & journey from Siberia (prison camp) to the middle east & eventually the UK (initially to Glasgow than London). I have looked at ships logs but cannot find his name.
I am very interested in finding out more about my own Polish heritage and would very much like to find out if the lady I met with the same ancestor name of Gociolowicz and me are related (as I think Goscilowicz is not a common name).
Thank you
